Background

Expansion joints, also called compensators or expansion joints. Consisting of a bellows (a sort of elastic element) and an end tube which constitute the working body thereof. The bracket, the flange, the conduit, the container and the like are subjected to dimensional change caused by expansion and contraction due to heat and the like, or axial, transverse and angular displacement of the pipeline, the conduit, the container and the like is compensated. And can also be used for noise reduction and shock absorption. Has wide application in modern industry. In order to prevent the pipeline from deforming or breaking due to thermal elongation or temperature stress when the heating pipeline is heated, a compensator is required to be arranged on the pipeline to compensate the thermal elongation of the pipeline, so that the stress of the pipeline wall and the acting force acting on the valve member or the bracket structure are reduced.

The common expansion joint is fixed by metal, so that the fixing is troublesome, the medium is smooth by using flange connection to ensure the sealing in the pipe, but the expansion joint is inconvenient because a circle of bolt holes are arranged on a flange plate and fixed by bolts, and the nuts and the bolts need to be disassembled one by one when the expansion joint is cleaned, thereby bringing unnecessary troubles and wasting time during operation.
